Whakaoti i te 3^2(5+12)-58/(frac{1{2}+5^2)div(3+21)}

$$\frac{ { 3 }^{ 2 } (5+12)-58 }{ ( \frac{ 1 }{ 2 } + { 5 }^{ 2 } ) \div (3+21) }$$

Aromātai

$$\frac{1520}{17}\approx 89.411764706$$

Ngā Upane Otinga

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{9\left(5+12\right)-58}{\frac{\frac{1}{2}+5^{2}}{3+21}}$$

Tāpirihia te 5 ki te 12, ka 17.

$$\frac{9\times 17-58}{\frac{\frac{1}{2}+5^{2}}{3+21}}$$

Whakareatia te 9 ki te 17, ka 153.

$$\frac{153-58}{\frac{\frac{1}{2}+5^{2}}{3+21}}$$

Tangohia te 58 i te 153, ka 95.

$$\frac{95}{\frac{\frac{1}{2}+5^{2}}{3+21}}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{95}{\frac{\frac{1}{2}+25}{3+21}}$$

Me tahuri te 25 ki te hautau \frac{50}{2}.

$$\frac{95}{\frac{\frac{1}{2}+\frac{50}{2}}{3+21}}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{50}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{95}{\frac{\frac{1+50}{2}}{3+21}}$$

Tāpirihia te 1 ki te 50, ka 51.

$$\frac{95}{\frac{\frac{51}{2}}{3+21}}$$

Tāpirihia te 3 ki te 21, ka 24.

$$\frac{95}{\frac{\frac{51}{2}}{24}}$$

Tuhia te \frac{\frac{51}{2}}{24} hei hautanga kotahi.

$$\frac{95}{\frac{51}{2\times 24}}$$

Whakareatia te 2 ki te 24, ka 48.

$$\frac{95}{\frac{51}{48}}$$

Whakahekea te hautanga \frac{51}{48} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{95}{\frac{17}{16}}$$

Whakawehe 95 ki te \frac{17}{16} mā te whakarea 95 ki te tau huripoki o \frac{17}{16}.

$$95\times \frac{16}{17}$$

Tuhia te 95\times \frac{16}{17} hei hautanga kotahi.

$$\frac{95\times 16}{17}$$

Whakareatia te 95 ki te 16, ka 1520.

$$\frac{1520}{17}$$

Tauwehe

$$\frac{2 ^ {4} \cdot 5 \cdot 19}{17} = 89\frac{7}{17} = 89.41176470588235$$
